The present invention relates generally to hinges and more particularly to a hinge for use in mounting a screen or a storm door in position in a door frame.

In the construction of brick and other types of buildings, it frequently occurs that the walls thereof are of materially greater thickness than the door frames which are mounted therein with the result that the edges of the door frame, upon which the screen or storm door is hingedly mounted is spaced inwardly from the corresponding face of the wall. Because of this construction, a screen or storm door, which is mounted on a conventional hinge will contact with the adjacent corner of the wall and is arrested thereby. Thus, when the screen or storm door is swung violently open as by wind, the same is likely to be materially damaged by engagement with the wall due to the strain or stress exertedthereon at a point closely adjacent the hinged connection with the door frame. If the door itself is not damaged, it frequently occurs that the hinge is pulled loose from the door and which has associated therewith a coil frame.

The primary object of this invention is to provide, in a manner as hereinafter set forth, a door hinge embodying a novel construction and arrangement of parts, whereby the door may swing to a position substantially parallel with the wall of the building under all conditions, said hinge including a break joint which is engageable with the building wall spring which normally maintains the break joint in inoperative position.

Other objects of the invention are to provide a hinge of the character described, which will be simple in construction, strong, durable, highly efiicient in its use, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention may become apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a horizontal sectional view through a portion of a building wall and door frame, showing, in top plan, a hinge constructed in accordance with the invention mounted in position.

Figure 2 is a view in top plan of the hinge and door,showing said door and hinge in open. position substantially parallel with the wall of the building, the latter being shown in horizontal section, together with the door frame.

Figure 3 is atop plan view on an enlarged scale, of the hinge in closed position.

Figure 4 is a front elevational view of the hinge in closed or inoperative position.

Figure 5 is a top plan view of a door and hinge in accordance with this invention, showing the manner in which the hinge functions when the door is opened the usual distance.

Referring to the drawings in detail, it will be seen that the reference numeral 1 designates a portion of a building wall having formed therein the door opening 2, in which is mounted the frame 3, which is recessed as at 4.

The hinge is designated generally by the reference numeral 5, and comprises an end supporting leaf 6, for engagement with the frame 3, in the manner best illustrated in Figure 2 of the drawings, said leaf 6 being provided with openings or holes 7 for the passage of screws for anchoring the same to the frame. The leaf 6 is further provided with the knuckles 8, which cooperate with the knuckles 9 formed on the intermediate leaf 10, for pivotally connecting the leaves 6 and 10, together through the medium of the pintle 11. The leaf pin is of angular form, and the portion thereof which carries the knuckles 9 is adapted for abutting engagement with the leaf 6 when the door is in. closed position. The other angular portion of the leaf 10 provided with the openings 12, for thepassage of suitable securing elements for mounting 'a door stopping strip 13, in position. i

It is understood, of course, that two or more of the hinges are utilized for mounting the door in position in the frame.

One edge of the stop strip 13 is adapted to abut the leaf 6, when the door is in closer position, as clearly seen in Figure 1 of the drawings.

The leaf 10 has formed integrally on its upper and lower edges the right angularly disposed apertured ears 1 1, which co-act with the apertured cars 15, on the leaf 16, having openings 17 therein, for the passage of securing elements for connecting said leaf 16 to the door which is designated by the ref rence numeral 18. The apertures in the ears 14 and 15 of the leaves 10 and 16 are, of course, vertically aligned for the passage of the pintle 19, for pivotally connecting said leaves together. The ears 15 are formed integrally on the upper and lower edges of toe leaf 18 and are disposed substantially at right angles to said leaf 16. The upper edge of the leaf 16 is disposed below the horizontal plane of the upper edge of the intermediate leaf 10 and the lower ed e of the leaf 16 disposed above the horizontal plane of the corresponding edge of the leaf 10. The ears 15 are disposed adjacent the inner sides of the ears 1 1 of the leaf 10. The ears 1% and 15 extend toward each other, in order that the overlapping effect may he had.

A coil spring 20 encircles the pintle 19 and has one end operatively engaged with the leaf 10 and its other end engaged with the leaf 16 in a manner to yieldingly urge said leaf 16, into inoperative position. The swinging movement of the leaf 16, on the leaf 1(), under the impulse of the coil spring 20 is limited in one direction by the door 18, which will abut the stop strip 13. lit will thus be seen that the leaves 10 and 16 provide a break joint between the strip 13 and the door 18.

hen the door 18 is swung open in the usual manner, as in Figure 5 of the drawings, the strips 13 and said door 18 will swing in unison. lVhen the door is swung open, a greater distance than is usual, the building wall 1 will be engaged in the manner best illustrated in Figure 2 of the drawings, by the hinge constituting this invention, and the door will be permitted to swing to a position substantially parallel with said wall 1., against the tension of the coil sprin 20.

It is believed that the many advantages of a hinge in accordance with this invention will be readily understood and although the preferred embodiment of the invention is as illustrated and des ribed, it is to be understood that changes in the details of construc tion may be had, which will fall within the scope of the invention as claimed.

lVhat is claimed is: V

1. A hinge of the character described comprising an intermediate leaf and a pair of end leaves hingedly connected to the opposite ends of the intermediate leaf, one of the end leaves adapted to be mounted on a door frame, the other of the end leaves adapted to be secured to the door, a spring operatively engaged with the last named end leaf, in a manner to yieldingly urge the same in one direction, relative to the intermediate leaf, and a stop strip mounted on one side of the intermediate leaf for abutting engagement with the door, in a manner to limit the swinging movement of the last named end leaf, under the impulse of the spring.

2. A door hinge of the character described comprising an angular intermediate leaf, an end leaf hingedly connected to one end of the intermediate leaf, and adapted to be secured to the door frame, and being further adapted for abutting engagement by the intermediate leaf, in a manner to limit the swinging move ment of said intermediate leaf thereon in one direction, another end leaf hingedly connected to the other end of the intermediate leaf and adapted to be anchored to the door, a coil spring operatively engaged with the last named end leaf, in a manner to yieldingly urge the same in one direction relative to the intermediate leaf, and a stop strip mounted on one side of the intermediate leaf for abutting engagement with one edge of the door, in a manner to limit the swinging movement of the last mentioned end leaf under the impulse of the coil spring.

3. A door hinge of the character described comprising an angular intermediate leaf, a supporting leaf hingedly connected to one end of the intermediate leaf, and adapted to be secured on the door frame, integral apertured ears on the other end portion of the intermediate leaf, another end leaf, integral apertured ears formed on said other end leaf extending adjacent the ears on the intermediate leaf, a pintle extending through the ears on the intermediate leaf and the end leaf, the last named end leaf adapted to be anchored to the door, a coil spring encircling the pintle and having one end engaged with the intermediate leaf and its opposite end engaged with the last named'end leaf in a manner to yieldingly urge said last named end leaf in one direction relative to the intermediate leaf, and a stop strip rigidly mounted on one side of the intermediate leaf for abutting engagement with the door in a manner to limit the swinging movement of the last named end leaf, under the impulse of the coil spring. r

In testimony whereof I affix my signature.
